Intel 945 GMA chipset proformance issues

I replaced my windows xp with ubuntu 10.04 on my netbook, obviously not a very powerful computing platform, but it could run games like deus ex just fine. Now the desktop works pretty well, but even the visualboy advance emulator runs too slow to be playable. I've seen things about Intel chipsets not running well on Ubuntu, and done about a thousand Google searches, but I cant seem to find what's wrong. I have the Intel 945 GMA express mobile chipset.

I am using a lenovo 3000 n100 that I just set up to dual boot 10.04 and am having the same issue (same intel 945gm)- generally everything is working fine out of the box except the video acceleration- also 10.04 doesn't (at least by default) have an xorg.config that I have seen- I believe from what I have read it isn't used in the latest versions
